!The Movie

* AdaptationDisplacement: The film is better known than the original novel.
* SugarWiki/AwesomeMusic: This was one of Music/JerryGoldsmith's major movie scores.
* BigLippedAlligatorMoment: The scene with Box the robot doesn't quite fully qualify, as it explains what happened to the other people who escaped, but it still seems quite gratuitously weird.
* FunnyAneurysmMoment: Logan and Jessica re-enter the city by diving into the [[http://en.wikipedia.org/wiki/Fort_Worth_Water_Gardens Ft. Worth Water Gardens pool]], where twenty-eight years later four people drowned.
* InferredHolocaust: So, with the [[spoiler: city destroyed, how will the people survive when they can't fend for themselves]]?
* {{Narm}}: [[http://www.youtube.com/watch?v=4YsTKL7L6-o This]] "NOOOOO! Don't go in there! You don't have to die, well no one has to die at 30! You can live, LIIIIIIVE!"
** "All frooooozeeeeeeen!"
* NightmareFuel: Box, the cheerful-voiced caretaker robot in the ice cave, cheerfully informs Logan and Jessica that "It's my job... to freeze you!" Did we mention he's immune to blasts from Logan's gun?
** Carrousel itself. It doesn't look so much like people happy to reach "renewal" as people trying to claw their way out - and then they explode to the cheers of the crowd. Later, Logan finds out that [[spoiler:no one ever renews - then you realize that those people are dead, dead, dead.]]
* SpecialEffectsFailure:
** The small scale of the city models are painfully obvious and unintentionally make it look like a model train set. The opening at least [[ObscuredSpecialEffects tries to hide the scale with an out of focus lens]], but it only helps so much, and the rest of the film shows the model sets plain and clear. The water makes the city being a miniature particularly obvious since the surface tension/waves are out of proportion with the buildings.
** During one shot of the Carrousel scene, you can clearly see the wires holding some of the people in the air. When this footage was reused for the TV series, this was also visible. It's been speculated that this wasn't an error, and that the citizens were actually meant to be hoisted up on wires in order to attempt renewal.
** Box is convincing enough for the time, but in a close-up shot while he's talking you can see Roscoe Lee Browne's teeth.

!The TV Series
* Not-quite-as-SugarWiki/AwesomeMusic: The pilot and three other episodes were scored by Laurence Rosenthal, who is probably most well-known for ''Series/YoungIndianaJones''. His main theme sounds like the Disco version of [[Film/ANewHope Princess Leia's theme]] punctuated by blasts from the spaceship-gun in ''VideoGame/{{Asteroids}}''.
** Film Score Monthly [[https://www.screenarchives.com/title_detail.cfm/ID/3842/LOGANS-RUN-TV-Series-1977/ released the soundtrack album for the series]] (and the complete score for the movie as well).
* RetroactiveRecognition:
** None other than Creator/MichaelBiehn appears in the first episodes.
** Creator/KimCattrall makes an early TV appearance in one episode.
* ShipTease: Due to the desire to direct the series for a family audience, for most of the series, the romance between Logan and Jessica is downplayed to the extent that any overt expressions of affection between them could be considered ship-teasing. It's not until the episode "Futurepast", one of the last episodes to be broadcast, that Jessica actually says she loves Logan (and not to her face). Ironically, the episode spends more time shipping the RidiculouslyHumanRobots Rem and Adriana (a one-off guest character). (After that, the Jessica-Logan relationship becomes more overtly romantic, however).
* SpecialEffectFailure: Logan's vehicle is supposed to be a hovercraft, yet wheels are clearly visible in some distance shots.
* WhatDoYouMeanItsForKids: While the series in general is aimed at families, the episode "Carousel" is closer in tone to the movie, with a graphic death as well as a rather frank discussion about how Jessica may need to sleep with Logan in order to determine if his memories can be restored (and she eventually attempts to seduce him while wearing a disguise that involves an outfit far skimpier than she normally wears - a design closer in fact to what the movie version of Jessica wore).

!The Book
* AdaptationDisplacement: The film is much better known than the original novel, and many are unaware that two sequel novels, ''Logan's World'' and ''Logan's Search'' exist.
* HilariousInHindsight: Anyone who has played either of the first two ''VideoGame/BioShock'' games should find the description of Molly, the decaying city on the ocean floor, rather familiar.
